Introduction to the working voltage and precautions of electric heating tubes

Today, the editor will talk about the working voltage and precautions of electric heating tubes:

(1) Multiple series power supplies, for a group of electric heating tubes or electric heating tubes connected in series to the power supply, the working voltage of the electric heating tube refers to the voltage connected to this group of electric heating tubes specified in the design.

(2) Single power supply, for a single electric heating tube connected to the power supply, the working voltage of the electric heating tube refers to the voltage connected to the component specified in the design, that is, the rated voltage

Note: This involves the issue of whether multiple electric heating tubes are connected in series or in parallel. Therefore, when judging the voltage, if multiple electric heating tubes need to be connected, it is necessary to consider whether to connect in series or in parallel in order to determine the voltage of a single electric heating tube.

According to the data, currently 40% to 50% of customers who purchase electric heating thermal oil heaters are first-time users. Customers have many questions before and after use. In order to solve this problem, Yancheng Xingtai Electric Appliances will explain to you the methods and precautions for the first-time use of electric heating thermal oil heaters.

When using for the first time, please pay attention to whether there is water in the temperature control equipment, because many customers will use water for pressure testing and leak testing, so it must be cleaned before use; before filling oil, check the open and closed status of all valves on the heat transfer pipeline circulation system to ensure that they are in the correct position before filling oil;
